The rates of both compressor fouling and performance loss are a result of the variation in environmental conditions, fuel used, machine operating scenario and maintenance practices. Performance loss during normal operation is minimized by periodic on-line and off-line compressor water washes. Performance loss during extended operation is expected to be greater for plants that are located in humid and/or ) contaminated industrial environments. Also, plants operated under non-ideal running scenarios, along with neglected or poorly performed maintenance practices can be expected to exhibit increased performance losses. Plants that are sited in relatively clean less humid environments, operated within equipment design recommendations and cleaned with regular on and off-line compressor washes will experience less performance degradation. Performance recovery, beyond that which occurs with normal maintenance, including on and off-line washes, can be achieved following other off-line procedures. One procedure in particular involves removing both the compressor and turbine casing to accommodate hand scouring of the compressor rotor and stator airfoils. Compressor inlet air filter cleaning/replacement, along with other required maintenance, may also be performed during these inspections. Such an outage would most likely coincide with hot gas path or major inspection intervals, since significant machine disassembly is required. 7 A typical gas turbine operation profile, reflecting on- and off-line maintenance procedures, is presented in the attached figures. Plant performance degradation during normal operation is cyclic as impacted by on- and off-line compressor water washes. Drawing 519HA772 represents expected performance loss, in accordance with the stated basis for operation, maintenance and testing procedures. Note that this curve represents the locus of points following specific shut down maintenance activities, not actual continuous on-line operating capability. Drawing 519HA744 represents a comparable locus of data following the more extreme machine disassembly and hand scouring procedure.GENERATOR OUTPUT AS A FUNCTION OF COLD GAS TEMPERATURE 2Pole 3000 RPM 90000 KVA 11500 Volts 0.800 PF 0.480 SCR 275 Volts Excitation 40 Deg.
